Abstract: The disclosure concerns a greenhouse which defines an enclosed growing area covered by a structure including an external framework of convex shape in transverse cross-section, and a plurality of flexible light-transmitting panels arranged to form a covering at the inner side of the framework. The frame work includes a plurality of curved members extending transversely of the structure in parallel longitudinally spaced positions and forming rafters of the structure, and a plurality of parallel elongate members extending longitudinally of the structure and attached to the rafters. The light transmitting panels are each snap-fitted between adjacent ones of said longitudinal members of the framework in an outwardly bowed configuration.
